CFC’s

NOAA finds rising emissions of ozone-destroying chemical banned by Montreal Protocol Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new NOAA study shows. Trichlorofluoromethane, or CFC-11, is the second-most abundant ozone-depleting gas…

From NASA Goddard: Warm Air Helped Make 2017 Ozone Hole Smallest Since 1988 Measurements from satellites this year showed the hole in Earth’s ozone layer that forms over Antarctica each September was the smallest observed since 1988, scientists from NASA and NOAA announced Friday. According to NASA, the ozone hole reached its peak extent on…

From the “it’s that Methane and Ozone Emergency again” department, comes this breathless headline, for a kitchen sink press release that even includes the obligatory faux sinking atoll of Tuvalu. I had to laugh at the first line of the PR, that said: Even if there comes a day when the world completely stops emitting greenhouse…

Guest Opinion: Dr. Tim Ball My grandmother told me “Your sins will find you out.” I don’t know if it’s original, but it certainly seems true when you look at the sins of those who created the ozone hole and global warming deceptions. Exposure of the sins is not surprising because many of the same…

From the “possible measurement error” department. Larry O’Hanlon (via AGU blogs) writes: Something strange has happened to the atmospheric concentration of a newly discovered, human-made, ozone-destroying gas: it has suddenly dropped and nobody knows why. The gas, HCFC-133a, is a type of hydrochlorofluorocarbon, ozone-destroying compounds used in some industrial processes, including the manufacturing of refrigerants.…

From the “everything causes global warming” department….except, the effect they are claiming is miniscule compared to business as usual emissions in the USA. For example, they say in the PR: “…released 6,600 metric tons (7,275 U.S. tons) of [CFC] gases stored in insulation, appliances and other equipment into the atmosphere.” First, this plot from NOAA…

Image Credits: NOAA – National Weather Service – Climate Prediction Center By WUWT Regular “Just The Facts” On the heels of Andrew Dessler’s Ozone Hole tweet, we have from the BBC: “Researchers from the University of East Anglia have discovered evidence of four new gases that can destroy ozone and are getting into the atmosphere…

A new modeling based paper in Atmospheric Chemistry and Physics takes on that question directly. Of course the result is another “saved the world” moment according to some: [ Source: http://twitter.com/AndrewDessler/status/442342191067693056 ] I certainly don’t have a problem with reducing CFC’s, but Andrew Dessler’s comment speaks to the hero syndrome some of these scientists seem…

NASA Reveals New Results From Inside the Ozone Hole – Dec. 11, 2013 NASA scientists have revealed the inner workings of the ozone hole that forms annually over Antarctica and found that declining chlorine in the stratosphere has not yet caused a recovery of the ozone hole. More than 20 years after the Montreal Protocol…

From the make up your freaking minds department comes this oopsy juxtaposition of alarmist messaging. In an attempt to explain “the pause”, researchers are now grasping for explanations: Human actions that were not intended to limit the greenhouse effect have had large effects on slowing climate change. The two world wars, the Great Depression and…
